Answer:

The probability that Terry buys a sandwich and gets the bus is 0.36

Step-by-step explanation:

When two events are called independent, it means that the happening of one event doesn't affect the happening of other event.

Let A be the event that Terry buys a sandwich

Let B be the event that Terry gets the bus

Then

[tex]P(A) = 0.4\\P(B) = 0.9[/tex]

When two events are independent, their probabilities are multiplied i.e.

[tex]P(A\ and\ B) = P(A) * P(B)\\= 0.4 * 0.9\\= 0.36[/tex]

Hence,

The probability that Terry buys a sandwich and gets the bus is 0.36

Answer:Section 6.1

Solutions and Hints

by Brent M. Dingle

for the book:

Precalculus, Mathematics for Calculus 4

th Edition

by James Stewart, Lothar Redlin and Saleem Watson.

If you remember nothing else from this section remember:

arc length = radius * angle

s = r * q

where the angle, q, is measured in radians.

There are other formulas, but that one is pretty important.

48. A circular arc of length 3 feet subtends a central angle of 25.

Find the radius of the circle.

Start with s = r*q , s = 3 feet, q = 25 = 25*(p/180) = (5/36)p radians

3 = r * (5/36)p Å 3*(36/5) = r*p Å 21.6 = p*r Å r = 21.6/p feet

52. Memphis, Tennessee and New Orleans Louisiana lie approximately on

the same meridian. Memphis has latitude 35 N and New Orleans 30 N.

Find the distance between the cities, given the radius of the earth is

3960 miles.

Again start with s = r*q,

with r = 3960 miles and q = 35 – 30 = 5 = 5*(p/180) = (1/36)p.

and we need to find s = arc length = distance between the cities.

s = 3960*(1/36)p = 110p miles.

60. A sector of a circle of radius 24 miles has an area of 288 square miles.

Find the central angle of the sector.

For this you need a new formula.

The area of a sector of circle = A = ½*r

2

*q ,

where q is the central angle of the sector measured in radians

and r of course is the radius of the circle.

For this problem r = 24 miles, A = 288 sq. miles and we need to find q.

288 = (½)*24

2

*q Å 288 = 288*q Å 1 radian = q (or about 57.3)

62. Three circles with radii 1, 2 and 3 feet are externally tangent to one

another. Find the area of the sector of the circle of radius 1 that is

cut off by the line segments joining the center of that circle to the

centers of the other two circles.

So you start out with:

Notice you know the length of ALL the sides of the triangle, because you know

the radius of each circle. From this you might discern that: 5

2

= 3

2

+ 4

2

. Thus you

have the (length of the hypotenuse)

2

= (length of side A)

2

+ (length of side B)

2

.

And from that you may conclude the triangle is a right triangle, or rather the angle

we are interested in is 90. Thus we use the area formula given in the text:

The area of a sector of circle = A = ½*r

2

*q ,

For this problem r = 1 foot, q = 90 = p/2, and we need to find A

A = ½ * 1

2

* p/2 = p/4 square feet.

Step-by-step explanation:

The linear speed of a point on the equator in miles per hour is 1037 mph. Therefore, option D is the correct answer.

Given that, the radius of the earth is approximately 3960 miles.

Linear speed is the measure of the concrete distance travelled by a moving object. The speed with which an object moves in the linear path is termed linear speed. In easy words, it is the distance covered for a linear path in the given time. Linear Speed Formula is articulated as s=rθ/t.

Any point in the equator would complete a 360° or 2π, revolution in 24 hours. Therefore, the linear speed would be s=rθ/t.

where r is the radius of the Earth and θ is the angular distance (in rad) after time t

Hence, the linear speed would be

s= (3960×2π)/24

= (3960×2×3.14)/24

= 24868.8/24

= 1036.7

≈1037 mph

The linear speed of a point on the equator in miles per hour is 1037 mph. Therefore, option D is the correct answer.

Let's calculate the fraction of science fiction books in the library based on the given information.

If 2/5 of the books in the library are fiction, then the fraction of fiction books in the library is 2/5.

Now, if 1/4 of the fiction books are science fiction, we can find the fraction of science fiction books in the library by multiplying the fraction of fiction books by 1/4:

Fraction of science fiction books = (2/5) * (1/4)

Fraction of science fiction books = 2/20

Simplifying the fraction, we get:

Fraction of science fiction books = 1/10

So, the fraction of books in the library that are science fiction is 1/10.

None of the provided options match the correct fraction. The correct fraction is 1/10, which is not listed.

required Value of x is x=8

Step-by-step explanation:

We are given two points: (5,8) and (x,14) and slope =2 . We need to find value of x.

The formula used to find slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We are given slope =2 , x₁=5, y₁=8, x₂=x, y₂=14

So, we actually need to find value of x₂. Putting values in formula and find value of x

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\2=\frac{14-8}{x-5}\\Solving:\\2(x-5)=6\\2x-10=6\\2x=6+10\\2x=16\\x=\frac{16}{2}\\x=8[/tex]

So, required value of x=8

Step-by-step explanation:

(2x+15)=135    They're corresponding angles so they equal/congruent

     -15   -15       Subtract 15 on both sides since you're looking for x

2x = 120       Bring down the remains and subtract 135 from 15

Answer:

John need to get 293 in his next game to bring his average up to 183.

Step-by-step explanation:

John starts with N games played and averaging 177 points per game.

In game N+1, John scored 199 points.

[tex]\frac{177N + 199}{N+1}=178\\177N+199=178N+178\\N=21\\[/tex]

So, John has now played (N+1) = 22 games.

We need to know what score John needs in game 23 to bring his average to 183.

[tex]\frac{177*21 + 199+Y}{23}=183\\3916+Y=4209\\Y=293\\[/tex]
